useful Improvements in Printing-Machines,- fully described andrepresented inthe fol lowing specification and the accompanyingdrawings, forming a part of the same.

This invention relates to certain,improve-- ments in printing machines.a o c, It IS frequently (lGSlI'flblQtO assoclate with the product of ahigh speed web print ng machine, additional sheets, such, for in-"stance, as a cover sheet or a specially print ed sheet. This hasbeenaccompllshed heretofore by employing a pair of cutting cyl inders,one of which operates as a collecting cylinder, the web product of thehigh speed printing machine, and; the sheet ;or sheets to be associatedtherewith, being both delivered to the collecting cylinder and beingassociated thereon This construction is, however, open to the objectionthatthere is danger that the cutting devicesfon the cylinders referredto Will trim the cover or specially printed sheet during the collection.

It is the object of this invention to pro duce a mechanism foruseinprinting ma chines, in which specially printed sheets may beassociated with collected sheets,

these sheets being the product of a high speed printing,machine and todo this in such a way as to avoid trimming the spe cially printedsheets. g

lVith this and other objects inyview, the invention consists in certainparts, improve ments and combinations such as will be here inafterdescribed and more particularly pointed. out in the claims hereunto ap--pended.

(lo-acting with the forwarding cylinder?) before" referred to, is acollecting cylinder 8, this cylinder being mounted on ashaft '9.

This cylinder will be provided with sheet! taking devices, such, forinstance, as ordi nary pins indicated at 10.

i The printing mechanism is not shown, but the web coming from the highspeed print ing mechanism is indicated at This web may pass betweenbending rollers 11 and drawingrollers 12.

"Web cutting devices will be employed'in machines embodying theinvention, and, while the location of these devices may be varied, inthe particular construction shown they are monnted on the cylinders 2and S. In the part cular constrnctlon Illustrated,

the cylinder 8 is provided with a knife, in-

dicated at13, and the cylinder 2 with cuttingawoods, indicated at 14.VViththe mechanism as so far described, thef'web lVwill be forwarded,cut into sheets, and collectedon the cylinder 8, and,

after the desired number of collections have beenjmade, the sheets willbe taken by the pins 3. or 4, as the case maybe, and forwarded andfolded off by the forwarding cylinder 2. e it v l Machines embodying theinvention will be provided with means for forwarding sheets forassociation with the sheets whichhave beendelivered to the forwardingcylinder after collection by the cylinder 8. This sheet forwardingmechanism lmay vary in construction. As shown, a pair ofjforward-i ingcylinders 15 are employed, these rollers operating to forward the weblV, which runs at a lesser surface speed than the sur -j V face speed ofthe web lV. From these forwardingcylinders 15, the web is led between apair of cutting cylinders 16, 17, these cylinders being mounted onshafts 18, 19. These cylinders 16,17 convert the web into sheets, andthese sheets are delivered between a pair of guides 20, 21. The sheetsmay be fed between the g'uidesEZO, 21 by means of a cylinder 22, thisCylinder being mounted on a shaft 23, carried inspring bearings 24, andcooperating with the cylinder 17. The cylinder; 17 may be. provided withsheet-taking pins, indicated at 25, and

the guide 20 may be shaped, as shown, so

asto act as a stripper to take the sheets from these pins. An ordinarysheet-retaining guide, as'26; may be employed in connection with thecylinder 17.

" Inasmuch as the sheets which are formed in the particular constructionshown, by the cutting rollers 16, 17 are running at a lesser surfacespeed than the sheets cut from the webWVwith which they are to beassociated,

it is necessary' that these sheets be brought upto the speed of the websheetst While this may be, accomplished in various ways, in theparticular construction shown two cylinders 27, 28 areemployed forthispun pose, the cylinder 28 beingprovided with the usual sheet taking pins29. These cyline ders are so timed that the pins meet and take theforward end of the sheet which is being advanced between the guides 20,21, and, as these cylinders are running at the shown.

theyvill ng the sheet up'to th -f Speed. of these cyli d I At the timewhen the pins take these sheets, they should be released from the'actionof the forwarding cylinder 22, which, as has been before pointed out,may ed operate with the cylinder'17. In order to effect this, the shaft19 may be provided with acam, as 30, this/cam cooperating with adisk'iil on the shaft 23 before referred to,

of the cylinder 22. Q The cam 3O is so timed that its high part willstrike the disk 31 at the instant when the pins '29 take the sheet whichis being passed between the guides 20, 21. The highp'art ofthe camoperating on'this disk 31 will force the shaft 23 back against itsspring bearings, thus releasing the sheet from the nip of the cylindersAn ordinary sheet guide 32 m ay'be'-employed, and this guide maybe soconstructed and-located as to assist in holding the sheets both onthecylinder 2; and cylinderEZ'S, as
